Everything in the world right now is creating challenges for peace on this floating rock we all share our existences on; poverty, hunger, violence, racism, corruption, social & gender inequalities, socioeconomic status - the list goes on and on.
Let me remind you all again that every passing stranger or being or animal or insect or single-celled organism here on Earth has been through some kind of struggle in their life, and is mostly likely currently encountering some kind of troubles. We share that with each other, so don't shame or hurt one another for it, help each other and build each other up.
Send a smile to these people today, let a little bug outside instead of stepping on it - spread some love - maybe even give someone a hug; whatever you're comfortable with, spread some kind of peaceful emotion or interaction with the world today.
